Recycling Water
Project Ⅰ
Project Background：
A technology company in Kunshan works on research, manufacture and sale of polarizing sheet, optical functional film, and optical compensation film for LCD.
In 2016, SCHW undertook the company’s KI recycling water project (10m³/h), provided equipment such as power equipment, quartz sand filter, activated carbon filter and RO skid. Besides, SCHW also provided services such as engineering design, installation and commission.
The construction of this project started in October 2016, completed in March 2017.
